TAKING-UP DEVICE FOR CIRCULAR LOOMS.

Application filed January 10, 1928. Serial No. 245,641.

This invention relates to a taking-up device for circular loom, whereinthe completed tubular fabric is ositively propelled toward the taking-uprol lers by special means.

According to the invention, a plurality of propelling rollers arearranged above the beating part of the loom and are connected to eachother to form a polygonal unit, each roller being provided at both endswith bevel gears meshing with those of the adjacent rollers, and adriving shaft is operatively connected to at least one of saidpropelling rollers so as to cause simultaneous rota-tion of allpropelling rollers, whereby the tubular fabric engaging with saidpolygon of propelling rollers is positively propelled toward thetaking-up rollers.

The accompanying drawings illustrate a constructional example ofthe'invention by way of example, in which:

Figure 1 is a front view of the circular loom fitted with the deviceaccording to this invention,

Figure 2 is an enlarged detail view, J

Figure 3 is an end view of one of the propelling rollers shown in Figure2. i

In the circular loom shown in Figure 1, 1 is the base or bed, on whichis supported an upright shaft 2. On the upper part of said upright shaft2 is provided a ball 3, on which is swingably mounted a slay sole 5having a circular reed 4. Secured to the upright shaft 2 is an arm 6carrying a lifting roller 7 which, engaging with the under side of theslay sole 5, imparts a gyratory movementto the latter during therotation of the upright shaft 2. The tube of warps Ais operated bysuitable shedding mechanism for forming a shed successively, and theshuttle B is automatically moved through. the shed formed in the warpsalong the circular reed 4, in such a manner that the shedding motion isalways produced atthe point where the shuttle B is at the moment.

The invention will now be described as applied to the above-mentionedtype of circular loom, but it is to be understood-that the invention maybe applied 'to other vari ous' types of loom for weaving tubularfabrics.

Referring to Figures 2 and 3 as well as Figure 1, above the beating partof' the 100m are provided a plurality of propelling rollers 8 which areoperateively connected to each other to form a polygonal unit, eachroller 8 being rotatably mounted upon the bearing bracket 9, and beingprovided on each end with a bevel gear 10 integral with or fixed to it.Each roller 8 is'connected to two adjacent rollers by the engagement ofsaid bevel gears 10 at the ends thereof, as shown in Figure 2. One ormore of the propelling rollers 8 is operatively connected to the drivingshaft'll by the engagement of the bevel gear 10 on one end of the Oilroller 8 with the bevel gear 12 fixed to the inner ,end of the drivingshaft 11, thus it will be seen that by the rotation of the driving shaft11 all the propelling rollers 8 will be simultaneously driven. i

- The driving shaft 11 is operatively connected to the slay sole 5,through suitable mechanism, in such a manner that the driving shaft 11is rotated according to the move-- inent of the slay sole 5. But, it isto be understood that the driving shaft 11 may be driven from any otherpart independently of the slay sole 5. 5

Arranged above and beneath of. the polygon of the propelling rollers -8are guide rings 13, which serve to cause the tight engagement of thetubular fabric witli'the said propelling rollers 8, so that the tubularfabric is moved step by step toward the taking-up rollers during therotation of the propelling rollers 8.

While the gear'drive is shown for securing simultaneous rotation of thepropelling rollers 8. it may be if desired replaced by any frictionaldrive. a

- \Vhat I claim is A taking-up device for a circular loom,

wherein aplurality of propelling rollers arearranged above the beatingpart-of the loom and are connected .to each other to form a pol gonalunit, each ,rollerbeing provided at oth ends wi hbevel gears meshingwith those of the adjacent/rollers, and a' driving shaft is operativelyconnected to atleast one of said propelling rollers so as to causesimultaneous rotation of all propelling rollers, whereby the tubularfabric engaging with said polygon of propelling rollers is positivelypropelled toward the taking-up rollers.

In testimony whereof I alfix my signature;
